“…As noted during the current study (Expt. 1) and for other plant species (Harvey and Nowierski, 1988;Ku et al, 2007;Samarakoon et al, 2016), the inadequate accumulation of chilling can result in delayed budbreak, decreased percentages of buds forming shoots, and slow or weakened shoot growth. For commercial application purposed, it will be important to quantify the chilling requirement and the corresponding plant responses of other cultivars of clematis because varieties may respond differently, as also noted for other plant species (Gariglio et al, 2006).…”
